Create an interactive application using Shiny that does basic visualization of the data layers. We expect to use the leaflet mapping library and new geographic formats for raster (cloud-optimized GeoTIIFFs or COGs) and vector (PMTiles). Both of these new GIS formats take advantage of HTTP Range Requests to enable fast access to a simplified tile at any zoom level that is stored in the file (but only that part of the file is read). This enables both the reading and visualization of dense spatial data layers using only a simple web server to access the file and a lightweight JavaScript mapping library. The task of applying color ramps to COGs is handled swiftly by TiTiler.
